After 3 hours, you will be on 450 mile marker.

Step-by-step explanation:

step 1: At start, the number in the mile marker is 100

step 2: After 4 hours, the number in the mile marker is 300

step 3: The difference of 300-100 = 200. In 4 hours you crossed 200 mile markers.

step 4: Therefore, for 1 hour you can cross = 200/4 = 50 mile markers.

For 3 hours, the number of mile markers crossed = 3*50 = 150 mile markers.

step 5: After 3 hours, the number in the mile marker will be = 300+150 = 450
